About us

About us


We started in 2004 with a small, passionate team and a vision to “generate change” in the Australian energy market place.  Our first step was to design, build and construct our own biogas powered, GreenPower Accredited renewable generators in Northern Victoria.

As climate change, carbon tax and renewable energy political debates started to boil up, we focused on supporting new, clean and efficient renewable generation that we believe will become even more important to Australia’s energy mix as old, tired coal generators close down.

Our vision to “generate change” challenges the big electricity retailers as new demands from homes and businesses empowered by new technology, start to take control of their energy spend.  We identified an opportunity to create a unique business – an electricity retailer supporting renewable generation derived from Australia’s pure, natural resources. Pure Power from our natural resources can be generated clean and with lower cost.

So today, in addition to our own renewable generators, we support many other innovative renewable technologies utilising pure solar, wind, wave and bio-energy sources (you can find out more about these projects here).  We aim to source more electricity from renewable generators than the total amount consumed by our home and business customers.  It is exciting to know that the more customers we have, the more renewable generation we can support.

Our environmental performance is supported by numerous awards including our high ranking in the Greenpeace Green Electricity Guide and the winning of the 2010 United Nations Best Business Environmental Initiative (have a look at our awards here). You can also read about our sustainability principles here.

Our passion and ongoing support for renewables has enabled us to create a team and partners with extensive knowledge and experience in the renewable industry. For example, working with our solar partners, we help customers enjoy hassle free transition to solar to ensure they get the most out of their solar investment.  Thanks to our customers and our generators, solar currently accounts for the majority of our renewable generation capacity.

We also continue to keep abreast of further developments in renewables, energy storage and energy management and look forward to introducing even more innovative Pure Power products.

By supporting us, our customers have taken a simple step to make their electricity spend count. Every day they are supporting renewable generation whilst enjoying competitive rates and great service for their homes and businesses.
